Abstract
A system for measuring the strain in a structure in which the temperature at the location the strain is measured is also measured in which an optic fiber is incorporated in the structure which has an interferometer positioned at the point or points where the strain is to be measured. A pulse of light is sent down the fiber and the backscattered light is split to separate the Raman Scattered Spectrum light. The interferometer is used to measure the strain and the Raman Scattered Spectrum light is used to measure temperature and loss.
